Which of the following health benefits result from regular engagement in muscular fitness activities?

Regular engagement in muscular fitness activities significantly contributes to the prevention of bone density loss. This benefit is primarily linked to how resistance training and weight-bearing exercises stimulate bone remodeling and improve overall bone strength. The mechanical stress placed on bones during these activities promotes the deposition of minerals, enhancing bone mineral density and reducing the risk of osteoporosis and fractures, particularly in older adults.

While other options presented do relate to health benefits in various physical activities, such as aerobic exercises for cardiovascular health or specific dietary practices linked to cancer risk, they do not specifically address the direct relationship between muscular fitness and bone density. Resistance training is particularly effective in mitigating bone density loss as it provides the necessary stress and stimulus required for healthy bone maintenance.
